The single, overwhelming fact of history is the crucifixion of Jesus Christ. There is no military battle, no geographical exploration, no scientific discovery, no literary creation, no artistic achievement, no moral heroism that compares with it. It is unique, massive, monumental, unprecedented, and unparalleled. The cross of Christ is not a small secret that may or may not get out. The cross of Christ is not a minor incident in the political history of the first century that is a nice illustration of courage. It is the center.
The cross of Christ is the central fact to which all other facts are subordinate. -- TRAVELING LIGHT / Eugene H. Peterson, God’s Message for Each Day: Wisdom from the Word of God (Nashville: Thomas Nelson, 2006).
